PATENT OFFICE EDWARD W. STR'UBE, OF LONG ISLAND, NEW YORK INCINERA'IOROHU'IE AND DRAFT APPARATUS Application filed March 29, 1930. Serial No.439,938.

This invention relates to an incinerator chute and draft apparatus, andits principal object is to provide means whereby garbage and wastematerial may be'dumped into a chimney passage and conducted into a firechamber, and means for conducting the exhaust gases of combustion fromthe said fire chamber into the aforesaid chimney passage where thenatural upward draft will convey it to the chimney vent and to theout-door atmosphere.

Another object is to provide means for an under draft from a point belowthe chute mouth where it may pass freely and clear of any soggy orcongested material which may have accumulated in the said mouth when thethe incinerator is filled in excess of its normal capacity. 7

Another feature of the invention is a buffer element so positioned as tooverlap the vent from the under draft channel, and one, or moredeflecting buffers in the combined chimney flue and chute.

Another novel element is an automatic closure which shuts off areceiving hopper from the chimney chute.

A further improvement which adds safety and efficiency to the apparatusis a swinging panel suspended over the discharge mouth of the chute andbehind the lower intake door and adapted to prevent the outburst of anymaterial which might be dropping down the chute at a moment when thesaid intake door had been opened for the dumping of waste matterdirectly into the incinerator.

The foregoing and other objects and features of the invention will bedescribed in detail in the following specification and 5 claims, andillustrated in the accompanying drawings, in which Fig. 1 shows anincinerator installed in a cellar and adjacent to a combined chimney andchute. The upper portion on the incinerator is shown in section and thechinmey chute and principal elements of the invention, together withportions of the lower structure, are also shown in section to betterdisclose their construction and the manner in which they function.

Fig. 2 is an enlarged front view taken with in the limits of the line 22of Figure 1.

Fig. .3 is a section on the line 3-3 of F igure 2.

Fig. 4 is a plan View, partly in section on the line 4-.4 of Figure 3.

Referring mainly to Figure l of the drawings, the apparatus is describedas follows:

"A combined chimney and chute passage is shown at 10, the foundationwall of the build ing is seen at11;'earth outside the said wall is shownat 12 and the kitchen floor ofthe building at 113'; the kitchen at 14and the cellar at 15. It is, of course, not necessary that the intakehoppers should be in a kitchen, although the chimneys into which theyopen usually pass upward adjacent to that portion of the house.

The apparatus may be installed in conat18; but'for use in apartmenthouses and such buildings there may be'as many intake hoppers asrequired for the various floors and living rooms which they serve, thearrangementbeing; in line, one above another.

.Itwill be seen that at the base of the chimney chute, an opening 20 islocated and throught-his opening an inclined ofiset element 21 isinserted and secured in position. This inclined element has a lowerfloor 22 which extends from the chute mouth 23 to a point below thebuffer 24 which overlaps it, avent being provided thereunder as seen at25. This fioor 22 is slightly curved upward at 26 an-dis supported oncross bars 27. Beneath the fioor 22 is provided an under draft passage28 which draws exhaust air and gases from the fire chamber at a pointbelow the chute mouth 23. Vhen soggy material is piled up in the firechamber and chute mouth, the draft directly up the inclined chute isgreatly obstructed; but when this occurs, the under draft 28 serves toproduce efiicient and adequate combustion.

The inclined chute 21 is attached at its base to the top lid 30 of theincinerator, and a direct intake door 31 is provided as shown. Suspendedbehind this door and over the mouth of the chute element is a swingpanel 32 pivotally hung at 33. This swings easily forward, or back topermit of the passage of material into the fire chamber. Should a personopen the door 31, at a moment when material was in passage from an upperfloor, the said material would strike the panel 32 and be deflected sothat it would not burst out of the open door 31. This is also a safetyprovision, as it prevents the knocking open of the door 31 in case itshould have been left insecurely fastened.

The buffer 34 deflects falling material and diminishes the force of theblow when it strikes the floor 22.

An automatic closure door 36 is pivotally hung within each upper intakehopper as that shown at 18. These doors are hung out of the line of thechimney chute and are slightly inclined and rest at their lowerextremities against the base of the hoppers. They prevent combustiongases, smoke or the like from entering the rooms when the hopper lids 37are open, and they also prevent particles of garbage or like materialfrom upper floors, from flying out in the event of such material beingin passage at the time when a hopper lid was open.

As indicated by the arrows 38 and 39 respectively, it will be seen thatmaterial drops as at 38; while smoke and exhaust gases rise as at 39through the combined chimney and chute 10 as illustrated in thedrawings.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is as follows:

1. In combination with an incinerator and a combined chimney and chute,an oflset element connecting the passage channel of the said chimney andchute with the said incinerator, an inclined floor in the said ofi'setelement, an independent draft passage below the said floor and having avent discharging into the said chimney and chute, and a deflectorelement positioned above and overlapping the said vent.

2. In an apparatus of the class described, an inclined ofi'set chuteelement connecting a combined chimney and chute with an incinerator andadapted to conduct material in passage to the combustion chamber of thesaid incinerator, a. floor in the said offset chute element, anindependent draft passage below the said floor, a vent opening from thesaid independent passage into the said chimney and chute, a bufferelement positioned above the said vent and partially overlapping thesame, an intake door opening into the baseportion of the said ofi'setchute ele-.

'combu'ston chamber and to discharge the said draft into the saidchimney and chute.
